Thanks for your help! I was able to change my pressure back to where I'm more comfortable.
I recently got an S9 with a humidifier but for some reason I sleep better with my old machine......weird!

I have an old resmed remstar lx that I got back in 2000-2001. The only 2 buttons it has is a ramp button and an on/off button. It also has a small hole on the side. Long story short, I need to change the pressure and was wondering if anyone could insruct me on how to do so. Any help would be greatly...
